Icteric flare-up in patients with biliary atresia after hepatic portoenterostomy.

The relapse of icterus may be a sign of serious postoperative complication after hepatic portoenterostomy for biliary atresia. To analyse the cause of such icteric flare-up, a retrospective study was made on 27 patients. A total of 38 episodes of icteric flare-up occurred in 19 patients. An accompanying disease, which had not directly involved the biliary tract, was assumed to be the cause in 11 episodes (29%). Fourteen episodes (37%) were due to biliary tract infection caused by the cyst formed at the porta hepatis (5 episodes) or so-called ascending cholangitis (9 episodes). The other 13 episodes (34%) were free from both accompanying disease and signs of biliary infection. Among them, the cause of icteric flare-up was the cyst at the porta hepatis in one episode, scar tissue formation at the porta hepatis in 9 episodes and undetermined in 3 episodes.

Treatment of cystic hygroma and lymphangioma with the use of bleomycin fat emulsion.

Of the several types of treatment for cystic hygromas and lymphangiomas, surgical excision has been the preferred treatment. However, there is a high recurrence rate because lymphangiomas tend to infiltrate the surrounding tissues. Bleomycin in a microsphere-in-oil (S/O) emulsion was used in this study as a sclerosing agent for lymphangiomas. Experimental studies using domestic rabbits showed that the bleomycin emulsion caused more marked fibrotic changes at the injection site than other formulations, such as a blank emulsion and bleomycin solution. In clinical trials, 27 of 33 patients received bleomycin S/O emulsion injected directly into the tumors with satisfactory results. Histologic pictures of the clinically resected specimens confirmed the findings of the experimental studies. Comparative studies of treatments between bleomycin S/O emulsion and surgery indicated that injection therapy of bleomycin S/O emulsion would be more beneficial than surgical excisions.
